I have the exact same problem, I have set an enemy AI that uses tracing on its mesh when attacking to trigger a “deal damage” event but it doesn’t work when the tracing itself is out of camera. It’s a huge problem since my prototype is in first person. So I can just stand there, having an enemy attack my back and it won’t trigger any event. If I switch to the debug camera and see the enemy and the tracing, the event triggers again. If I look away with the debug camera, it stops triggering.
I wish I had known that before building a combat system on traces…
